If someone says that he will compete if the rules are changed, based on experience, I do not believe him. People who want to compete, will find a way, and no matter what is done, no matter what they say, those that have the means and don't typically won't. I get particularly irritated when people who I know have been offered the use of equipment so that they can try a sport, decline and then carry on about rule changes. The expansion in benchrest typically happens from club score matches that include various classes, starting with factory, including modified, and full custom. If someone is really interested in competition, organizing one of these sorts of events does not require much. Once shooters have gotten a taste, they can decide if they want to progress to more technical and demanding versions of bench shooting.
